Which Virtual Machine Manager do you use?

DiggDigital

Are there any free or open source virtualizers?

Mainly have used VirtualBox (open source & free) at home. Recently have started using VMWare vSphere ESXi (free version) a bit as well.

I only use Proxmox (open source & free) on my dedicated servers, that is if I use any virtualization at all.

Plenty of others to choose from. I think oVirt is another big one. Probably just depends on your usage and your support needs.

There's lots of Open Source platforms that allow you to launch and manage VM's from KVM, Xen, LXC, and many more types of hypervisors.

Here's a short list of some of them:

Web Based Interfaces:

• OpenNebula (Open Source)

• ProxMox (Open Source)

• OpenStack (Open Source)

• CloudStack (Open Source)

• VM Manager (Commercial)

• Xen Orchestra (Open Source)

Native Interfaces:

• VirtualBox (Open Source, Global OS Support)

• VMWare vSphere / VMware Workstation / VMWare Fusion (free and commercial editions)

• Citrix XenServer (free and commercial editions)

• Parallels Desktop (Mac support, paid)

There's also VirtEngine Open Source which we built that enables PaaS, STaaS and billing for providers and utilizes various open source technologies such as OpenNebula, Ceph, Docker, and many more to bring the best experience to the end-user.

We use virtpanel with KVM for customers and for our internal cloud, we use vmware vcenter & vsphere.

I use LXC on one of my home servers. It's free & opensource.
I also use qemu with kvm enabled on my desktop. (Yup, free & opensource) :-)

While we're on the discussion, do NOT use https://github.com/kimchi-project/kimchi for KVM. It's severely kludgey.
